This presentation is used as a basis for a course on drafting international commercial agreements. It is complemented by two cases studies. The course is mainly addressed to non lawyers and is hence rather practice than law oriented. The course is not linked to one jurisdiction or one type of contract in particular, but attempts to address general issues related to international commercial agreements. [less ▲]

se slides were used as support for a course taught in English (in 2011) which provides an overview of the major questions arising in the field of nationality law. The course focuses on acquisition and loss of nationality and touches upon other issues such as multiple nationalities and the influence of the European construction on nationality law. All these questions are studied using comparative materials (mainly from Western Europe) as basis. [less ▲]

This presentation serves as background for a short seminar (12 h) taught each year at the Moscow State Institute of International Relations (MGIMO) which purports to give a general overview of the achievements made so far in building a European private international law. The course is taught as part of the European law program offered by MGIMO's European Studies Institute which is co-sponsored by the College of Europe. Target audience of the course are Russian civil servants from different ministeries. [less ▲]

The aim of this exercise is to investigate different ways of ensuring the robustness of a frame building structure considering a vehicle impact on a column of the ground floor. The building is located at a corner of two roadways and thus the perimeter columns adjacent to these roads are likely to be impacted by a car or a lorry. Besides, the ground floor is a parking area (accessible to cars only) so that any internal column could also be damaged. The different approaches proposed in the Eurocodes will be applied and discussed. These methods consist for example in increasing the column resistance in such a way they can resist the impact or designing the structure so that it remains globally stable despite the loss of the damaged column. However, in such a case, a static removal of the column will be assumed (for sake of simplicity, no dynamic effect due to the failure of the column will be taken into account in this exercise).

Voltage stability refers to the ability of a power system to maintain steady voltages at all buses in the system after being subjected to a disturbance from a given initial operating condition [1]. Principal causes of voltage instability are [1-5]: heavy load system operation conditions, long distances between generation and load, low source voltages, and insufficient reactive power compensation. The degree of a system voltage stability (the proximity to voltage instability) is strongly influenced by system conditions and its characteristics such as: generation system characteristics (in particular excitation systems), load characteristics, reactive power compensation devices characteristics, voltage control devices, presence of under load tap changing (ULTC) transformers , etc.[4]. Usually, in a voltage unstable situation, the voltage magnitudes in some system buses undergo, generally monotonic, decrease in the seconds or minutes following a disturbance. When pronounced, this decrease might endanger the system integrity mainly due to protecting devices that trip generation, transmission, or load equipment leading eventually to a blackout in the form of a voltage collapse [2], [3]. Voltage collapse is defined as the process by which the sequence of events accompanying voltage instability leads to a blackout or abnormally low voltages in a significant part of the power system [1]. Voltage instability is considered as a mayor treat for secure power system operation in many power systems throughout the world. Taking advantages of existing technological solutions, such as synchronized phasor measurements, powerful computational facilities, networking infrastructure and communications, in order to monitor stability conditions and control detected instability are of paramount importance. Wide area monitoring, protection, and control systems open perspectives for effective solution of this problem [6]. [less ▲]
